Understand basic knot-tying terminology to make learning knots a breeze. Learning how to tie a knot on the internet is tough if you don't know the basic vocab. For this knot, you should know:
Bight: Simply a U-shaped bend, where the rope turns back on itself
Standing Line: This is the extra rope at the end of your knot. For example, if you were tying the noose at the end of a roll of rope, the standing line is the part leading back to the roll.

Pull out at least 3-4 feet of rope to work with. The longer the rope, the bigger the noose. Longer ropes also allow you to get more of the infamous coils around the top of the knot, which also makes it stronger.


3
Take the last two feet of rope (from the end) and make a simple S-shape. Take the end of the rope and create two bends, forming an S-shape with the rope. The standing line should be left long so that you have some string left at the end.


4
Take the standing line of the rope and pass it under all three sections of the S. Simply take the top end of the rope and bring it under everything, so that the S-shape in your rope rests on top of the standing line. This will slightly "ruin" the S shape -- what is important are the two bends.


5
Loop the end of the rope back around the top of the S-shape of rope and then back under. This is the first of the many "wraps" that sit at the top of noose. This is one revolution. Pull it tight, so that there is still the loop on one end.


6
Continue wrapping the rope around the S-Shape of rope 6 more times. Traditionally, a hangman's noose has seven wraps, but you can do it as many times as you want. You must, however, wrap it an odd number of times, otherwise you will not be able to finish the knot.
You must have at least 2-3 inches of the end of the rope left over when done.


7
Pass the end of the rope through the bottom loop of the noose. The bottom loop, means the loop next to the standing line of rope, leading away from your knot. Tuck the end of the rope through this bight.


8
Pull on the noose and standing line to tighten. This will also expand your noose hole, tightening the entire knot so that you're just left with the rope, the coils, and the noose. Once tightened, this knot is strong and difficult to undo.
If the noose isn't big enough, you should start over, making a larger S-shape than before.
